2 Conductor line cord. This supplies AC power to the console and has a
standard attachment plug on one end and a standard attachment receptacle on
the other.
2 Conductor cabinet power cord. This is used to furnish AC power to additional
power amplifiers, when the signal is supplied through a 3 conductor signal cable.
It has a standard attachment plug at one end and a 6 pole receptacle at the other.
For permanent installations, when the cables are to be installed in conduit,
special Jones fittings manufactured by the Cinch Manufacturing Company are
obtainable through your electrical supplier. Those recommended for console
location are:
1-5406 - CCE 6 prong socket
1-P406-WP 6 prong plug with wall plate
For each tone cabinet location:
1-P406 - CCE 6 prong plug
1-5406 -WP 6 prong socket with wall plate
BLOCK DIAGRAMS
Figure 1 is a simplified diagram showing how the console is connected to
a single tone cabinet or group of cabinets drawing not over 620 watts input.
This is the maximum AC power which can be supplied through the console
without damaging the console switch or wiring. The name plate on each cabinet
shows its wattage rating.
If the tone cabinet power requirements exceed 620 watts. some of the cabinets
must be supplied from a separate AC source as indicated in figures 2 and 3.
Figure 2 is the preferred method, employing a relay to turn on the additional
cabinets. The relay must have a coil of the same voltage and frequency rating
as the organ, and must have contacts suitable for carrying the amount of power
drawn by the additional cabinets. Allen-Bradley Bulletin 700 relays are suitable
for this purpose and may be obtained from your electrical supplier.
When the AC power is supplied separately to additional cabinets. as in figures
2 and 3, a 3 conductor cable is sufficient to carry the signal between cabinets.
DETAILED WIRING DIAGRAMS
Figures 4,5, and 6 are detailed versions of figure 1. In figure 4 the console is
connected to one tone cabinet having a single amplifier. and figure 5 shows
connections to a cabinet with two power amplifiers. connected together by a 5
conductor coupling cable. Additional amplifiers up to a maximum of 620 watts AC
input, may be connected as shown in Figure 6.
